R20 611.91
(R23 703.70 incl VAT)
Short description:

The MTP41S series is an extremely small and light pocket transmitter especially designed for professional wireless microphone applications.

01-WIR-TRA-004

MTP40S - MTP41S series are two extremely small and light pocket transmitters especially designed for professional wireless microphone applications.

Very easy and quick to use thanks to OLED display, dedicated buttons and a joggle selector.

MTP40S- MTP41S series benefit also of the latest Wisycom RF technology along with an enhanced robustness against noise and inter-modulation.
